Homework 12
· · Write a program that asks the user for a value (double) for x. The program should then ask the user for a value (integer) for N that is greater than or equal to three. As long as the user provides an invalid N, continue to ask until he provides a valid N. Once a correct N is provided, use a for loop to calculate the sum below and then print the answer.
